Okay here is some insider information: All four tires on my I-Pace were chunking not just the fronts. Also my service writer said there was a Land Rover/Range Rover getting new tires for the exact same issue when I asked her to evaluate the cause of the chunking. You definitely need to get your tie rods replaced and then a proper alignment for safety reasons. I have not read of any forum members needing new tie rods on their I-Pace especially with only 17,000 miles. I have double that mileage and all is good. When I got my new tires, I decided to get the alignment at the tire shop and within 7 days had my Jaguar dealership do another alignment. Look forward to the final chapter of your story.
